RADIATOR-CAP.

Specification of Letters Patent.

Patented Sept. 2, 1919.

Application filed April 17, 1918. Serial No. 229,164.

To all whom it may concern:

Be it known that we, Ismon M. JACOBS and WVILLIAM CRAMER, citizens ofthe United States, residing, respectively, at the city of Kansas City,county of Jackson, and State of Missouri, and at the city of St. Louis,in the State of Missouri, have invented certain new anduseful'Improvements in Radiator-Caps, of which the following is aspecification.

This invention is an improvement relating to the subject-matterdescribed in the appli- I cations of these same inventors for patentsfor radiators, Serial Nos. 197,542, and 198,649, filed, respectively, inthe United States Patent Office on October 20 and October 26, 1917.

In the accompanying drawings forming part of this specification, inwhich like numbers of reference denote like parts whereever they occur,

Figure 1 is a front elevation;

Fig. 2 is a front elevation with parts broken away, and with parts in adifferent position from that illustrated in Fig. 1;

Fig. 3 is a partial sectional view, one of the movable members beingshown in dotted lines in successive positions; and

Fig. 4 is a side elevation.

The object of this invention is to provide ready access to the radiatorneck of the inside radiator of the construction illustrated anddescribed in either of the above-mentioned applications for patent, orany similar construction. If the water in the radiator has become hot orsteaming, it may be objectionable to reach the hand in to unscrew theinside radiator cap 1 or a like member from its place on the neck 2, andto introduce fresh water into the radiator it is necessary to removewhatever kind of cap there may be on neck 2 or equivalent part. Thepresent construction, by allowing the folding back of straps 3, allowsready, free, and convenient access to neck 2 of cap 1.

Wings 4 on straps 3 encircle neck 2, and taper upwardly, so as to retaininwardlytapered cap 5 by frictional contact.

Cap 5 binds wings 4 together over cap 1 and neck 2 (as best seen in Fig.1), and this holds straps 3 in the position shown in Fig. 1 and in fulllines in Fig. 3.

Copies of this patent may be obtained for five cents each, by addressingthe The straps 3 are pivoted at 6 to the dummy radiator 7, whichcontains the inside or salvaged radiator 8. The relation of theradiators 7 and 8 to the hood 9 is that which is ordinary and common.

Cap 5 is finished at one end with the tit 10, having through it a hole11. When cap 5 has been removed from wings 4, it can be inverted asshown in Fig. 2, with the tit 10 inserted in the mouth of neck 2, whichenables the use of cap 5 like a funnel.

Having thus described this invention, we hereby reserve the benefit ofall changes in form, arrangement, order, or use of parts, as it isevident that many minor changes may be made therein without departingfrom the spirit of this invention or the scope of the following claims.

We claim:

1. The combination of a true and false radiator, the one inclosed by theother, and the false radiator having an opening near its top, strapmeans pivoted to the said false radiator and adapted to close the saidopening, a neck for the said true radiator projecting through the saidopening, and a cap adapted to bind the said strap means in closedosition and to inclose the said neck, the sai strap means havin wingsthereon and the said wings being inc osed within the said cap, the saidwings being exteriorly tapered and the said cap being interiorlytapered.

2. In combination, a false radiator provided with an opening, a trueradiator provided with a neck which extends through the opening, strapshinged to the top portion of the false radiator and provided at theirfree ends with wings adapted to embrace the neck when the opening isclosed, and a cap which embraces and holds the wings closed and whichincloses the top of the neck, said cap having a reduced extensionprovided with an opening and which may be inverted when the straps areopen and the reduced end fitted in the top of the neck to feed water tothe true radiator.

In testimony whereof we hereunto afiix our signatures.
